I would go for a noise-cancelling headset instead. I use the latest David Clark X-11 (List price about $750 USD but there are many cheaper one available that do a good job, I think). The old passive headsets are just not as good as these new active ones so that I wouldn't buy that model you are asking about. The X-11 is much lighter and more comfortable than the older models, albeit twice as expensive.
I went with David Clark rather than Bose (up-market) or the no-name ones (down-market) because I have used that brand for about 30 years and have always found them to be rugged and dependable, plus the service is good.
